19# Retrieve the requested information form the mmsdrfs file.
20#
21#   Usage:  mmsdrquery queryType itemList [scope [norefresh]]
22#
23# where
24#
25#   queryType   specifies the type of infromation requested.  The supported
26#               query types are defined in file mmsdrquerydef and can be
27#               specified using either the appropriate keyword or its
28#               corresponding integer value.
29#
30#   itemList    a colon-separated list describing the information that
31#               is to be returned.  The supported items are defined in
32#               file mmsdrquerydef and can be specified using the item's
33#               keyword or integer value.  The 'all' keyword is equivalent
34#               to requesting all currently defined items in the order
35#               in which they appear in the mmsdrquerydef file.
36#
37#   scope       can be used to limit the number of the returned items.
38#               The meaning and syntax of this parameter dependents on
39#               the query type:
40#
41#               - for sdrq_cluster_info the only valid value is 'all'.
42#
43#               - for sdrq_node_info the same syntax must be used as
44#                 for the -N option on mmchnode and similar commands.
45#
46#               - for sdrq_nsd_info the scope parameter can be either
47#                 a list of NSD names, a list of file system device
48#                 names, the keyword 'free_disks', or a fully-qualified
49#                 path name for a file containing NSD or device names.
50#                 All file system device names must include the /dev
51#                 prefix to distinguish them from NSD names.
52#
53#               - for sdrq_fs_info the scope parameter can be either
54#                 a colon-separated list of device names or one of
55#                 the 'all' key words: all, all_local, or all_remote.
56#
57#               If ommitted, 'all' is assumed for all query types.
58#
59#   norefresh   (optional) assume the cached mmsdrfs data is current.
60#
61#
62# The output consists of one or more records, containing the following
63# colon-separated fields:
64#
65#    fixed eycatcher  - the character string 'mmsdrquery'
66#    query type       - the value of the queryType input parameter
67#    error indicator  - if not zero, the rest of the record is undefined
68#    version number   - the value of $sdrq_current_format
69#    reserved field 1
70#    reserved field 2
71#
72# The remainder of the fields represent the values of the requested items
73# in the same order as they appear in the itemList input parameter.
74#
75# If an unkown request type is specified, the error indicator field
76# in the output line is set to 109 (ENOSYS).
77#
78# If the specified object in the scope parameter does not exist, the error
79# indicator in the output line is set to 19 (ENODEV).
80#
81# If an individual item is unknown, or is not supported any more,
82# the corresponding field in the output is set to "sdrq_unknown_item"
83# or "sdr_obsolete_item" respectively.
